To all whom it may concern:

Be it known that I, ROY M. DEAN, a citi- ,zen of the United States, residing at Chi- .Cago, in the county of Cook and State of lllinois, have invented certain new and use ful Improvements in Heaters for: Motor-Vehicles, oi which the following is specification.

This invention relates to improvements in heaters for motor vehicles and the like and one of theobjects of the same is to provide an improved device of this character em- 7 hodying a radiator constituting a foot rest, and having a non-circulating Water chamber therein, the water being heated by means or the exhaust gases from the engine, circulating through the radiator and out of commingling relation with the Water in the Water chamber.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists. in the features of novelty in substantially the construction, combination and ar rangeroent of the several parts hereinafter.

more fully described and claimed and shown in the accompanying drawings illustrating the invention and in which- 3 Figure 1 is a perspective ofan improved device of this character, constructed in accordance with the principles of this invention.

l ig. 5 is a vertical sectional view taken on the line 55, Fig. 6.

Fig. 6 is a horizontal sectional view taken an the line 66, Fig.

r Referring to the form of the invention shown in Figs. 1, 2 and 3, the numeral 10 designates a foot rest which may be of any desired size and configuration and constructed of any suitable material, but is preferably of a substantially triangular shaped form to term a rest for the feet. This rest is hollow and is provided with a casing 11 therein s'ze somewhat smaller than the outer rig and the bottom 12 of the outer casing .250 constitutes the bottom of the casing 1].. The Walls of the casing 11 cooperate with the Walls of the casing 10 to form a closed Water space therebetween' and an inlet 1.4:

is provided by means of which the Water chamber may be filled. The inlet is provicled with a removable cap 15 and the opening of the inlet, Where it extends into the casing 10, is spaced from the highest point of the casing 10 so that when the W8. ter chamber is filled with Water an air chamoer 16 will be formed above the water to Leading into the casing i1 is a pipe 19 which has communication with the exhaust pipe oi'the engine and a suitable controlling valve may he provided for controlling" the inlet of the exhaust gases from the exhaust pipe into the casing 11.

The casing 11 is also provided with an -1tlet pipe 20 so that the exhaustgases passing through the pipe 19 will circulate through the casing 11 and out of the pipe 20, and thereby heat the Water in the Water chamber 13. The overflow pipe 1? may he arranged in any suitable position and may be constructed in any, suitable manner but is preferably provided iwith a portion 21 in the form of a small "flexible metal tube adapted to he coiled around the pipe 20. This overflow pipe serves the tunetion of permitting the steam or vapors which be generated in the Water sass out of the space it. is overflow pipe is arranged in such a posi on that any motion given to the Water in the Water chamber by the movement of the vehicle, will prevent the water from swinging over the inlet of the overflow pipe.

The heater mi manner preferahl he held in any suitable means of feet or lunc ets '2 for securing Jill} heater to the floor.

In the form of the invention shown, in Figs. 4 to 6, the heater is shown as being embedded in the floor so that the top thereof will no tlush with. thejziiaor of the vehicle. In this form of the; inven tion, a suit" vehicie and opens through the door thereof. Arranged within this support is a casing 25 having a closed water chamber 26 provided with a fill inlet 27 and an overflow outlet 28, all similar in construction to the form shown in Figs. 1 to 3. The inlet pipe 29 corresponds with the inlet pipe 19 and the outiet pipe 30 corresponds with the outiet pipe 20. In this form of the invention the top of the water chamber 26 is spaced below the top 23 of the heater and shutters 31 similar to the ordinary registershutters may be provided for shutting ofi the supply of heat.

In this form of the invention the exhaust gases enter the pipe 29 and flow through the chamber 32 and out of the pipe 30. During this passage through the chamher, the water in the water chamber 26 is heated and the heat generated thereby is discharged into the vehicle and such discharge is controlled by the shutters or dampers 31. If desired heat insulating materiai 33 such as asbestos or the like may be provided either on the inside of the box 2% or the outside of the heater 25.

A suitable valve 34 may be provided in the bottom of the box 24: and is adapted to be opened to permit outside air to flow into the box and around the heater and through register or grating 23 when desired. When it is not desired to permit outside air to enter, this valv 84: is closed. While no operating mechanism is shown for the valve 34 it is to be understood that it may be operated in any suitable manner.

The inlet of the overflow pipe 28 is located at a higher elevation than the top of the fiilpipe 27, and which latter may be provided with a removable closure 35.

While the preferred forms of the invention have been herein shown and described it is to be understood that various changes may be made in the details of'construction and in the combination and arrangement of the several parts without departing from the spirit of this invention,

What is claimed as new is 1. In a heater for automobiles, the combination of an outer casing constituting a foot rest and heat radiator eiemenh, an in the inner casing and adapted to intense ner casing within the outer casin'g'providing a water chamber between the casings, said chamber being closed to the interior of the inner casing and adapted to form a, closed non-circulating Water space, means for introducing a supply of water into the space,

and means for circulating a heating medium 1 means for controlling the circulat-ionof said heating medium.

3. In a heater for automobiles, the combination of an outer casing constituting a foot rest and heat radiator element, an in nor casing within the outer casing providing a. water chamber between the casings, said chamber being closed to the int tior of iorm. a closed non-circulating water space, means for introducin a en l of water into the.

space, means for circulating a heating me dlum through the inner casing, and an overflow passage for the said water chamber,

4:. In a heater for motor vehicles, the combination of a radiator, said radiator em bodying a ciosed non-circulating water chamber, means for circulating the exhaust gases irom the engine through the heater out of commingiing relation with the water in said chamber to heat the water, and an overflow pipe for the water chamber, said pipe leading from a point above the normal level of the Water inthe chamber.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing "witnesses, on this 6th day or December, A. D. 1916.
